APPARATUS FOR PRODUCING ORNAMENTAL ROOFING.

To all whom it may concern.-

Be it known that I, WILLIAM P. DUN

LANY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Apparatus for Producing Ornamental Roofing, of which the following is a specification.

This invention relates to the art of roofing and refers more particularly to the production of ornamental flexible sheet roofing material of the character comprising a water-proofed base, coated with a granular or comminuted mineral substance to protect the water-proofing medium from the weather, and having an ornamental design applied thereto.

One of the objects of the invention is to devise an improved apparatus for creating a design on theroofing after the layer of grit has been affixed by applying an additional layer of coloring material in the form of the design on top of the coating of grit.

Another object is to provide an apparatus.

such as just set forth by which the design may be rapidly and effectively applied during the continuous traveling movement of the sheet about its guiding and feeding rolls. In the accompanying drawings, Figure l is a diagrammatic view illustrating an apparatus embodying my invention. Fig. 2 illustrates a fragment of the stencil, and Fig. 3 represents a fragment of roofing made in accordance with my invention.

In manufacturing roofing of this character a suitable base is selected, which base may consist of a strip or sheet of flexible absorbent material, such as paper, cloth, felt or other fibrous material. This strip is coated on one or both faces, or wholly or partially saturated, with a water-proofing medium, which may be of a bituminous, asphaltic or resinous composition, and which may be maintained in a fluid state by application of heat thereto. After the surface of the sheet has been coated or impregnated with thewater-proofing mediuma layer of comminuted flaky or granular mineral sub stance, or grit, such as silica, shale, crushed stone or slate, gravel or the like, is applied to the face thereof while the water-proofing material is in a fluid or viscous condition, so that the grit will adhere to the base. The roofing is now ready to receive a suitable ornamentation which may be of any Specification of Letters Patent. Patented Fab, 6, 1917, Application filed Novembei 6, 1915. Serial No. 59,933.

preferred design or configuration.-- For exand the roofing sheet move along together and at a certain point they come into association with a spray head from which a spray of coloring material or paint, preferably of a bituminous nature, is continually discharged. The supply of paint may be maintained in a suitable tank located in a plane above and connected to the spray nozzle, the paint being maintained in a fluid condition by application of heat to the tank.

The spray issuing from the spray head Will pass through the open spaces in the 'stenciland will saturate the layer of grit on the roofing and become intimately associated with the substratum of waterproofing or binding medium. A stronger bond between the layer of grit and the base will thereby be effected.

Referring to the drawings: The apparatus illustrated in Fig. 1 comprises a series of rolls between and about which the strip or sheet of felt or other base material 5 passes and by which the sheet is given a continuous traveling movement. 6 indicates the initial rolls, from which the sheet 5 passes down around rolls 7 located in a tank 8 which contains an asphaltic or other binding medium 9. Heat may be applied to the tank in any desired way to maintain the binder in a molten condition. After being immersed in the binding medium the sheet may be passed upwardly, and, if desired, may be lapped back and forth around a suitable number of rolls 10 allowing the binder to cool. The sheet then passes beneath a hopper 11 containing the granular mineral substance. The hopper 11 is as long as the sheet is wide so that a layer of grit will be deposited upon the, entire sheet. The thickness of the layer of grit on the sheet may be controlled by placing. the lower end of the hopper, or an independent scraper, close to the upper surface of the sheet.- Rolls l2vmay be provided to roll the layer of" grit into close association with the binder. The grit-coated sheet now passes into operative relation to the design applying means. This comprises a stencil 13 which is preferably in the form of an endless ribbon of the same width as the sheet 5 and which is supported upon a suitable number of rollers 14:, the latter being driven at the proper speed so that the stencil and the sheet 5 move at the same rate. In the present instance a roller 15 is provided above the stencil and the sheet 5 is thereby caused to travel with the stencil along the lower, vertical and upper sides of the rectangular figure in which the stencil is held by its mounting rolls.

A spray head 16 which is preferably positioned beneath the upper run of the stencil is arranged to eject upwardly a spray of paint across the full width of the stencil and the sheet 5. The spray head may be supplied by a tank 17 located in a plane above said head and connected thereto by a valved pipe 18, the tank containing a quantity of bituminous paint which may be maintained in a fluid state by applying heat thereto in any well-known way.

The stencil may be kept clean by a pair of rotary brushes 19 contacting opposite sides thereof. Any matter loosened by said brushes will fall into receptacles 20 therebeneath.

The paint ejectedfrom the spray head 16 will pass through the interstices in the stencil and will saturate the coating of grit on the roofing and unite with the bituminous binder of the base. In this manner a permanent and durable design may be rapidly applied tov the roofing during the continuous travel thereof about its feeding and guiding rolls.

The foregoing detailed description is not intended as a limitation of my invention to the present disclosure. I

The scope of the invention is pointed out in the appended claims.

I claim as my invention:

1. An apparatus for producing ornamental sheet roofing comprising means for causing a flexible base to travel between two points, means for applying a binder to said base, meansfor depositing a material upon the base to form a background, a stencil positioned in close proximity to the background-carrying surface of the base, means for causing the stencil to travel with-the base, and a paint spraying nozzle positioned to discharge coloring matter upwardly through said stencil, the binder applying means, the back ground applying means, the stencil and the nozzle all being located between the tWo points of travel of the base.

2. An apparatus for producing ornamental sheet roofing comprising means for causing a flexible base to travel between two points, means for applying a binder to said base, means positioned to subsequently deposit a background upon said base, a paint container provided with an upwardly pro- Yjecting discharge nozzle, an endless ribbon stencil positioned in close proximity to the background-carrying surface of said base, and means for causing said stencil to travel around said nozzle and with said base.

In testimony whereof, I hereunto set my hand in the presence of two witnesses.
